Advantages of Busbar Trunking System*Busbar Trunking System is highly recommended, adopted and consulted by many consultants and become a integral part of Green Building ConceptSupported By: Electrical Times (UK), Modern Building Services (UK), ESDS (India), Electrical Engineering Portal# Heat , Fire & Safety# Short Circuit withstand capacity# Energy Efficiency# Flexibility# Installation# Service life# Space requirement

*There are 4 classes of fire:Class AOrdinary combustibles or fibrous material, such as wood, paper, cloth, rubber, and some plastics.Class BFlammable or combustible liquids such as gasoline, kerosene, paint, paint thinners and propane.Class CEnergized electrical equipment, such as appliances, switches, panel boxes and power tools.Class DCertain combustible metals, such as magnesium, titanium, potassium, and sodium. Heat , Fire & Safety

Energized Electrical Equipment Bus ductHeat , Fire & SafetyHeat : Increased temperature of conductor can lead to fire in case of poor insulationMost common Insulations used in sandwich Bus Bar Trunking system: Note : Use of Class F insulation or Class H insulation can increase the service factor or the ability to withstand high ambient temperature conditions.

Class B130 C - This has a form that inorganic material is hardened with adhesives Eg. Mica.Class F155 C Made of Class-B materials that are upgraded with adhesives, silicone, and alkyd-resin varnish of higher thermal endurance. Eg. - Combination of Mylar & Nomex Class - H180 C Made of inorganic material glued with silicone resin or adhesives of equivalent performance Eg. Epoxy.

Epoxy Insulation compound - HKE 455Various grades of epoxy compound when mixed in different combination give different results,

Our Epoxy HKE 455 is a compound ( In House ) made from polymeric component , chlorine, carbon, calcium, silicon and aluminium.

High with stand capacity : 10000 volts / layer,

Very high tensile strength : 23000 psi

Excellent resistance to most chemicals & moisture,

High flexibility for temperature extremes : - 5C to 180 C

Does not become brittle with age.

Class F insulation 155 C Ref. Ambient of 40C + Allowable temp. Rise 105C + Allowance for Hot spot of 10C Example : 40 oC + 105 oC + 10 oC = 155 oC

7. Life of epoxy compound is more than 25 years.

8. No corona effect due to extrusion process used for insulating conductors

9. Any possible problems due to pin-holes is prevented at QC by passing each piece through a 5kV HV test for 60Sec.

10. Each and every single piece is tested for 5kV (60Sec) as part of routine test prior to dispatch clearance.

11. RoHS compliant.
